Application of Industrial Air Springs in Conveyor Belt Equipment

Application scenarios:
Conveyor belt equipment often vibrates due to material impact, motor vibration or mechanical transmission during operation, especially in high-speed, heavy-load or long-distance conveying scenarios.

Solution: Install air springs at equipment support points (such as drive devices, brackets or frames) to absorb vibrations using their compressibility and damping characteristics.

Effect: Reduce equipment structural fatigue, reduce noise, and protect key components such as conveyor belts and bearings.

Typical Application Cases

Long-distance conveyor belts in mines:
Air springs are used at the drive roller and redirection roller to alleviate the impact force during start-stop and prevent belt tearing.

Automated warehousing and sorting lines:
The height of the conveyor belt is adjusted by air springs to meet the needs of different sorting stations.

Heavy material conveyors:
Dynamically balance the load to avoid structural deformation caused by uneven material distribution.
